The former Disney princess welcomed the world's press to question whether she's had some silicone stuffing in the bra region by going braless in a plunging gown.

Selena, who turns 22 on Tuesday, exposed plenty of cleavage with a heavily embellished gown that was slashed to the waistband.

Attending the Ischia Global Film and Music Festival in Italy, the on-off girlfriend of Justin Bieber dazzled in the diamond-studded number, but left us in no doubt that she's attempting to vamp up her image.

As well as the plunging back confirming that Selena had left her bra at home, a slash to the thigh showed off nearly every inch of toned leg as the singer posed for the cameras.

And while attending the Gala Dinner Awards at the festival, the starlet turned full-on vixen as she sat down to flash even more leg.

Rumours have been swirling that Miss Gomez has gone under the knife to boost her cup size after pics of a braless Selena looking astonishingly perky surfaced.

But the Wizards of Waverly Place star doesn't seem to be shy about flaunting what her mama – or indeed, her doctor – may have given her.

Earlier in the week, the brunette directed more attention towards her chest by donning a completely see-through top.

NOT SO INNOCENT: Selena's shirt was totally sheer at her press conference [WENN]

Posing at a press conference for her new film Rudderless, Selena's lacy white bra was perfectly visible through a floral shirt that could have been prim and proper if it weren't totally sheer around the rose petals.

Teaming the shirt with a near-sheer feathered skirt, Selena seemed intent on showing off as much flesh as possible.

Fast forward a few months, and we bet Selena will be swinging into arenas on hot dog balloons a la Miley Cyrus.
